Please note that this webinar was previously recorded, but has been made available so more people can access this valuable, practice-changing information.
Who's It For?
If you work with parents (IBCLCs, breastfeeding counselors/educators,
nurses, midwives, doulas, doctors, or any perinatal professional),
this webinar is for you.
Pumping discomfort is such a challenge for families,
and guess who gets the frantic phone calls--YOU!
Now there’s actual data proving a better way to size flanges…and it’s not the old “just add X millimeters” approach.
If your Clients Ever Say:
- “Pumping hurts.”
- “I don’t know if this flange is the right size.”
- “I’m not getting much milk.”
…then this webinar is a must-attend.
What You'll Learn
- The History of Flanges and Breastpumps - who invented them and why that matters
- Traditional vs. New Sizing Methods - and why the old method is failing families
- Flange Market Overview - what options are available for families and professionals to choose from
- The Evidence Behind the "Smaller Flanges" Approach - first-of-its-kind research
- How YOU Can Learn How to Better Support Your Clients - an updated approach, using the now-available tools
Who's It For?
If you work with parents (IBCLCs, doulas, nurses, midwives, or any perinatal pro), this webinar is for you.
Pumping discomfort is driving families nuts, and guess who gets the frantic phone calls? YOU!
Now there’s actual data proving a better way to size flanges…and it’s not the old “just add X millimeters” approach.
If your clients ever say:
- "Pumping hurts"
- "Im not getting much milk."
- "I don't know if this flange is the right size."
…then this webinar is a must-attend.
Oh, and did we mention you’ll get 1 L-CERP*? Because you deserve professional credit for leveling up your skills.
Why You Need This Guide:
Enhance Client Comfort
Eliminate nipple pain/discomfort with a customized flange fitting, fostering a positive pumping experience.
Boost Milk Supply
Optimize pumping efficiency (duration of the pumping session), which will increase milk yield for some of your clients.
Professional Credibility
Provide evidence-based recommendations that build your clients’ trust and confidence in your care.
There has never been evidence for the “standard” flange sizes, and most of our clients need 13-17mm flanges…it’s RARE to need 18 or larger (they exist, but are not common).

The One Thing You Need to Understand
Flange size is not one-size-fits-all. Smaller flanges don’t just ‘feel better’; they can literally reshape pumping outcomes for your clients—faster results, higher output.
This single shift in perspective
will revolutionize how you approach flange fitting and dramatically improve outcomes
for your clients.
HOWEVER, it’s NOT just “go smaller”. The key is finding out how small and how to assess for which size (and shape) works best and feels best WITH your client!
The 3 Core “Secrets” You Need To Know About Flange Sizing
‘One-Size-Fits-Most’ Became the Standard—and It’s Failing Families
The real story behind pump manufacturers’ sizes is that no one seems to have questioned the flange size since two men invented the flange in the early 1800s. There’s never been a study looking at different size flanges–until now!
The Flange FITS™ Approach Outperformed Standard Sizing in Our Study
During this webinar,
you’ll hear the step-by-step breakdown of how we measured, tried different flanges, and observed flange fit for maximum milk output and comfort.
You’ll hear about the surprising “sweet spot”
in flange diameter that makes pumping painless—participants called
it “very comfortable or feels like nothing."
There Are Simple Strategies to Implement This Research in Your Practice Right Away
You’ll hear how to turn your new knowledge into
real-world results without needing fancy equipment or advanced credentials.
Why not make yourself
one of the local lactation heroes by solving a problem that has stumped lactation pros for years: “Why do some parents pump so little, so painfully?”
a special bonus for YOU!
Those who view the webinar will get a PDF summary of the research study plus 14-Day Replay Access*, and 1 L-CERP!
We would LOVE for you to join us if you can!
*Note: The replay will be available for viewing 14 days from the date of registration, NOT 14 days from when YOU start watching it. Instructions to access the recording will be emailed to you, so be SURE to check your junk, spam, promotions, and/or subscriptions folders.

Only ONE Live Session This Time...Don’t Miss It!
Imagine how your clients will feel when they finally find a flange fit that works—less pain, more milk, and way less stress.
“In our study, participants pumping with smaller flanges saw a mean increase of 15 grams more milk
per session—and rated their comfort as significantly higher!”
What Professionals Are Saying
[After the flange fitting] I was able to pump at a much higher power level than before -- for example, I wasn't able to go higher than 2 or 3 on my Spectra, but now I can go to 9, 10, sometimes 11 with no pain! It's wild! Before it would take many minutes for my letdown, and now it's nearly instant. I don't really know very well how much more milk I'm getting because I wasn't pumping regularly before the fitting because it was so painful and slow. However, I know for certain that it's much faster to get to 4 oz (sometimes less than 10 minutes total both sides while before I was lucky to get to 4 oz even after 20 minutes total). [Now] I feet a lot more in control and I understand more what is happening. So it gave me a lot of confidence and made it seem less...random and painful. Now that I'm back at work this is incredibly helpful and a relief as my baby is relying upon me pumping and I still need to actually get work done.

[The flange fitting session] ensured I found the right flange size for yield and comfort. Your consultation also helped be understand what to expect, what effective pumping looks like and how to actually use the pump features.
~ Brandy
I was using a flange that was too big for my nipples and I found pumping uncomfortable. When Jeanette gave me the proper size, I found pumping to be much more comfortable, and I was able to tolerate pumping for a longer period of time. This allowed me to collect enough milk to exclusively breastfeed my daughter, while working full time! Flange fitting changed my breastfeeding experience and allowed me to be successful in breastfeeding my daughter for 16 months (and counting!). I was so nervous to have to pump when I went to work full time, but with Jeanette's expert guidance, we found the right flange size that allowed me to be comfortable while pumping and helped me retain my milk supply.
